中途测试,下完测试管柱,管柱上一般要安装控制头,才能座封封隔器进行测试。在生产中,我们用方钻杆代替控制头,经过10多口井次的实践,让明是行之有效的方法。(有关指标参看表一)现作简单介绍,供现场工作的同志参考。具体作法:下完测试管柱,将方钻杆接在管柱上,在立管泵压表处接显示头,在钻台下方的循环高压管线上连接节流管汇,将节流管汇出口连接至计量池或计量罐。(参看示
Midway test, test tube under the column, the general installation of the control head on the column, in order to seal the packer for testing. In production, we use square drill pipe instead of the control head, after more than 10 well-logging practice, so that Ming is an effective method. (The indicators refer to Table 1) Now for a brief introduction for the work of the comrades for reference. The specific approach: the next test column, the square drill pipe connected to the column, the riser pump pressure gauge connected to the display head, under the drill pipe loop connected to the high-pressure pipeline throttling manifold, the throttle manifold The outlet is connected to a metering tank or metering tank.
